MAPREDUCE-7315. LocatedFileStatusFetcher to collect/publish IOStatistics. (#2579) 
Part of the HADOOP-16830 IOStatistics API feature.

If the source FileSystem's listing RemoteIterators
implement IOStatisticsSource, these are collected and served through
the IOStatisticsSource API. If they are not: getIOStatistics() returns
null.

Only the listing statistics are collected; FileSystem.globStatus() doesn't
provide any, so IO use there is not included in the aggregate results.

Contributed by Steve Loughran.
